This 1" diameter counterweight shaft upgrade minimizes flexure, increases stability, and significantly optimizes performance of the Atlas EQ-G GoTo Telescope Mount. The upgrade is thicker than the standard, 3/4" diameter shaft that comes with the Atlas EQ-G Mount for enhanced stability. Since the upgrade is not retractable like the standard shaft, it eliminates any potentially troublesome weight shifts during tracking of celestial objects, which can wreak havoc on tracking accuracy. The Shaft Upgrade features a threaded Declination axis collar to provide a more rigid and secure coupling to the Atlas EQ-G Telescope Mount. Its 13" length is a full 2" longer than the standard Atlas shaft, which allows use of fewer counterweights for balancing most astronomical equipment payloads. A large, threaded "toe-saver" knob at the end of the shaft keeps installed counterweights from falling on the ground (or your feet - ouch!), even if their lock knobs inadvertently become loose. On top of these great performance enhancements, the Counterweight Shaft Upgrade's attractive chrome finish also gives the Atlas EQ-G Mount a nice aesthetic boost.
